Look no more...
There's no better tape period, this is the real deal. Quality product, pricy, but worth every penny. I had multiple air bleed connecting seams, did my entire basement ductwork with 100 feet and some left over to do a few more seams. Get some little scissors to cut it with, makes life easier. The utility blade crumples the corners a bit, which makes it trickier to get the backing off. Hope this helps!

Very sticky
Great price for how much you get. Very sticky. Easy to use. I use on my hvac registers after cleaning them up. Keeps attic air out. Seems like quality product. Very strong. Does its job by making an airtight seal.

Excellent mastic tape!
Seals ductwork well, you will never get the ductwork apart. Thick glue with a good seal. Top notch.

Awesome stuff
This stuff is great! Seems good, flexible to get around uneven surfaces and mold to it/hold tight. Way better than the crappy little foil tape you get and the big box store.
